This is a listing of all the kinetic sculptures I have created since 1975. It is an archive of historical and current work. Most of these are no longer available for purchase because they were created in limited editions. Go to the Current Works page to see sculptures still available for purchase.

You will find photographs, possibly videos, and much more information on many of the sculptures by clicking on the "Click to read more..." link. I have limited information on many of the sculptures from the early years. They were created before video cameras!

About Focus

Focus uses a mechanism similar to the one I used in Tapestry but a bit more refined to make it quieter and longer running.

You wind Focus by holding the back wheel in one hand and turning the front wheel about 20 turns in the clockwise direction. Release the back wheel and the motion starts with the wheels rotating in the opposite directions. This continues until one or both wheels lose momentum and start rocking back and forth. This eventually triggers the mechanism and the wheels start counter rotating again. The type of patterns created varies with the somewhat random timing of the mechanism trigger.
